Actually, I just had a friend take a look at it and poke around with the dental pick, as well. He feels it's more like a shallow spot of "flake rust" as opposed to a full-out pit cavity.
I suppose I can live with it given its location, shallowness and the fact that the rest of the gun is in such nice shape. While it was disappointing to find any imperfections, I think I'd have to look for a long time to find a Belgian Sweet 16 in the same condition, so I'd better keep it.
I appreciate all your help, as always, gentlemen.
